3D Area Manager Enhancements in BoardSim
The 3D Area Manager now supports importing and exporting 3D area definitions, enabling reuse across designs and simplifying project setup. Users can also set the data folder path directly from the manager screen to ensure project consistency and better file organization.

Each 3D area now displays reference designators and solution status in dedicated columns, making it easier to track progress and area definitions. A new option to automatically select area nets allows users to instantly highlight relevant nets for faster visual analysis.
3D Area Statistics and Quick View Access
Users can now view detailed statistics for selected 3D areas, including overlap detection and area properties, directly within BoardSim. A quick 3D view of any area can be launched from within the BoardSim window, reducing the need to switch to 3D Explorer for basic visualization. For deeper analysis, 3D Explorer remains available.

3D Area GUI Based Connector Pin Placement
A new “Expert Properties” section has been added for users needing compatibility with earlier HyperLynx versions. Parameters such as solder ball diameter, layer thickness, and pin size can now be toggled or edited directly in the 3D Area interface. This ensures older projects remain accessible and editable without requiring conversion.
Advanced Port Options from BoardSim
Users can now modify external ports and reference configurations from the Advanced Port Options dialog within BoardSim. This avoids the need to launch Advanced Solvers separately and provides direct access to previously defined expert parameters for components.
Full-Wave Solver: Small Object Removal
A new command allows users to automatically remove small objects or edges that may interfere with simulation accuracy. The tool provides feedback on the number of objects removed per layer, helping users fine-tune models for better solver performance.
Free Cloud-Based Workshops on Xcelerator Academy
To help users get started and build confidence with HyperLynx tools, Siemens offers free, step-by-step workshops via Xcelerator Academy.

Advanced Creepage Analysis and 3D Rule Support
The creepage engine in version 2504 introduces significant updates. Violations are now shown more clearly using cyan, red, and gray paths to visualize net connections, including floating metals and cross-layer routing. The engine now works on partially routed nets and offers better performance. Two new parameters have been added: “Calculate Danger Zones” and “Exclude Constant Nets” for more precise rule control. All features are compatible with both 1 nm and 10 nm database configurations.
New IC Packaging Rules
New IC Packaging Rules
Two new out-of-the-box checks have been added for IC packaging:
- Exposed Vias checks minimum copper clearance when vias are embedded in planes.

- Missing Teardrop checks whether traces extending from vias include the required teardrop when certain length and width conditions apply.

Improved Integration with Allegro
HyperLynx DRC now synchronizes views with Allegro. When a violation is selected in HyperLynx, Allegro automatically displays the matching layer and zooms to the correct location. This allows quick updates within the layout tool. Embedded components are now shown in Allegro’s visibility settings, and tie-bars are automatically treated as series components for better rule processing.
HyperLynx Schematic Analysis
Faster Model Creation from Xpedition Schematics
Users can now automatically generate passive and connector models directly from Xpedition Designer schematics. This option is available in Project Creator dialog under the “Models” tab. It can cover up to 70 percent of the components in a typical design, helping teams start simulations faster.

Improved Simulation Data Structure
The simulation database has been restructured to allow multiple users to access and sync data within the same folder. This change supports parallel workflows and helps teams avoid conflicts during simulation setup.
Download Shared Files Without Full Checkout
Users can now download individual files without checking out the full simulation folder. This applies to commonly shared files such as stackup files, .bud, .ddr, .sws, and .ref files. With the right permissions, these files can be exported and shared directly with colleagues, saving time and effort.

Run Simulations Without Layout Check-In
Designers working on PCB layouts no longer need to check in their design to run simulations. HyperLynx now supports simulations on the latest saved layout version, helping teams avoid workflow interruptions and keep layout and simulation work in sync.
Enhanced PCB Version Metadata
A new column and property field display the PCB version metadata used in each simulation. This makes it easier to track which version of the PCB layout was used, improving traceability and project management.
